So Im working on a friends car,For some reason it has no spark and the fuel pump wont come on...The car has a brand new distributor on it and a brand new fuel pump relay and pump...What could be the problem...Ive tried searching but have came up with no straightforward answers....

main relay or bad key switch perhaps?

Ive tried a few different relays..one was brand new oem honda and also tried a few different ecu's...also put my aem ems in it pump came on...what do you think it could be....Im sure that one of the two ecu's other than my aem were good.....

sounds like a main relay issue.

Out of curiousity pull the fuel pump acces cover and make sure your getting voltage to the pump and trace the wires back to the main relay. Its possible to have a break in your wiring some where. Sorry just thought of that.

the aem doesnt really need all the same grounds as the stock ecu needs check to make sure that the ground that goes to the thermostat housing is grounded good then check the ground that goes to the tranny. other than that i dont know what it could be..

DID IT ACTUALLY START with the ems or just turn on the pump

Car wouldnt start...pump would infact cycle...So Im at a loss now....the car has all of the proper grounds...Im gonna try yet another ecu...
